摘要：

A D-A conjugated polymer (PThTPTI) was developed by using a brand new pentacyclic aromatic lactam acceptor unit (TPTI). PThTPTI possesses good light absorption, thermal stability, and a deep HOMO level. PThTPTI/PC71BM cells afford an outstanding PCE up to 7.80%, with high V-oc (0.87 V), J(sc) (13.69 mA cm(-2)) and FF (65.6%), and over 70% EQE in the range of 435-640 nm.
